HINGE.

Application led March This invention relates to a hinge adapted for use' in connection with windshields or ordinary swingable windows.

lt is an object of this invention to provide a simple structure having means for yield-- Figure 2 an enlarged elevational view of the hinge;

Figure 3 is an enlarged topplan viewer the hinge;

`Figure 4 is an enlarged sectional viewV iipo'n the line IV-IV of Figure 2;

Figure 5 is an enlarged fragmentary elevationalview of thehinge withV parts slio-wn in section; A

Figure 6 is an enlarged fragmentary elevational view of the hinge in a slightlyv modified form; and

Figure 7 is a part sectional and part ele vatioiial view ot a slightly modiied forni ot' the invention.

ln referring to the drawings, it will be observed that the hinge coinprisesa pair oit relatively movable or rotatable membersv l and 27 the former of which may constitute the stationary disk member while the latter may torni the movable member. These members are rotatably connected by a rivet 3. A plate or support 4 is positioned between the disk members l and 2 upon the same pivot 3. The lupper end of this plate is provided with a double headed stud 5 which projects upon opposite sides ot said plate. lt will be noted that the peripheries of the members l and 2 are `ot` substantially varcuate form at one end and the movable member 2 may be provided with suitable notches 6 upon such arcuate portion for vcooperation with the loop terminals 7 of a 12, 1926. Serial No. 94,109.

resilient detcnt 8 which is in the form "of a leaf spring confined between the rivet 5 and the periphery of the disk member 2 as shown in F ig. 5. Y

lt will be noted that the resilient detent S has an intermediate indented portion that engages about one-litth ot' the circumference ot the rivet 5 and that the heads of the rivets 5 extend over' the detent for confining the same in position. Another detent 8 having similar terminal loops 7 is confined between` the stationary disk member l and the rivet 5 upon the opposite side of the plate 4, as shown in Fig. 3. The two detents 8 coniprise friction producing means when iii engageinent with disk members l and 2.V

The two members l and 2 are provided with right angled attachinglanges la and 2L by means ot' which the saine may be attached to the relatively hinged parts. r i

lVliere considerable jar is encountered, for example in a windshield structure, it is desirable to provide the removable hinge memf bei' 2 with suitable recesses such as 6 for engagingthe spring detents 8.` However, in

ordinary windows in houses and the like.

where little shock and jar occurs, the mov able hinged member may be made with a smooth periphery as shown in Figure 6.

In Figure 7, there is shown a iiiodiiied structure. In this instance, the plate Il, corresponding to the plate 4, is provided with a slot 9 below the pivot 3 which is provided with a roll ll upon its shanlrior forming an abutment for a leail spring l2 positioned between the roll and the bottom oi the' groove. The top of the plate 4 is transverse ly split and the metal 4b onone side ofthe split is crimped over the stationary member l ot the hinge while the metal Lleon the other side ofthe split is `crimped over` the movable member 2c of the hinge. It will be obvious that the crimped portions of the plate et will be held in frictional engagement with the periplieries of the hinge meinbers by the spring l2 which, however, will vield sulliciently to allow rotative movement of the hinge members. r

It will be noted that inrits operative pos tion the stationary member l of the hinge is secured to the window frame and the 1novable portion 2 of the hinge is connected to the Window as indicated in Figure 1. Of course, it will be understood that each window will have a pair of such hinges arranged upon the opposite sides thereotl and in order to open the window it is merel),T necessary to rotate the same upon the pivot 3, the detents 8 or the plate a yielding 'for such a purpose. vWhen the window has been opened or closed to the desired extent the yielding detents or crimped portions le and l" ot' the plate l will engage the peripheryv of the movable hinge member and retain the same in adjusted position. In cases where the notches such as G are used in the periphery ot l the movable hinge member the detent will ot' course snap into such recesses for more seeurelv holding the window in adjusted position.

l am aware that'. man v changes may be made and numerous details ot' construction may be varied through a Wide range without. departing from the principles of this invention and I therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:

l. In a hinge, a stationaryv member, a plate pivoted to said stationary member, a stud carried by the upper portion ot' said plate, a swingable member coaxiallv pivoted with said plate, and a pair of resilient members engaged by said stud, one resilient member havingvielding terminals in engagement with said stationary member and the other resilient member having vieldable terminals in contact with said movable men'iber.

In a hinge, a pair ot' spaced relativel'v movable members, a plate positioned in the space between said members, a pair ot resilient members connected to said plate outside of said space, said resilient members trictionally engaging said movable members for controlling the relative movement thereof.

3. In a hinge, a stationarv support, a plate pivoted to said support, a movable member coaxial with said plate, a resilient member with the peri plierjv of said mov: ble member,

.said movable member having notches` 'for receiving the loops of said latter resilient member.

4. In a binge. a pair ol' .spaced relatively movable members, an intermediate member disposed between ,said members. a pivot element connected to said members. and l`rif tion producing means connected to .said intermediate member l'or engaging the peripheries of said spaced members lor controlling relative movement thereof.

5. In a hinge. a pair ot' spaced relatively movable members, an intermediate n'iember, a pivot element connected to said members, said relativelyv movable members having notched peripheries. said intermediate member having an end extending bevond said pcripheries` and resilient means connected to said end ol' the intermediate member for engaging .said notched peripheriesi (l. ln a hinge, a pair of spaced relatively movable members, a support; in the space between said members, and a pair otl vieldable delenls connected to said support outside of said space, each detent having two portions in contact with one oi said members.

In testimoiny whereof I have hereunto silbscribed my name.
